Birchwood Casey Off-Eye Optical Lens Filters 40/60/80 Kit;

Rarely do advanced shooters shoot with both eyes open. The advantage of both eyes open is 3-D depth perception, field of view and peripheral vision. Binocular vision gives us the ability to pick up on a moving target quicker and react more accurately and efficiently. For shotgun, rifle, handgun and archery. This patented product allows full-time use of a dominant aiming eye and allows the shooter to keep both eyes open. Off eye filters are the first shooting aid designed to not block your vision but to hone the way your eyes perceive the target.
